No access for millions as payments via mobile service launches

Twenty million bank account holders will have no immediate access to the new Paym mobile payment technology, which officially launches on Tuesday.

The technology allows people to pay or receive money using a phone number, but without giving out their bank details.

However around 30m customers of banks including Barclays, Bank of Scotland, Halifax, HSBC, Lloyds, Santander or TSB will now be able to use the service, as soon as they have registered their mobile number with their bank.
